[sympy] General Relativity package based on Sympy

2011-03-08 Thread Alexander Gallego
Hi. I discovered Sympy just a few months ago, and I'm impressed. I started to develope a General Relativity package based on Sympy at my University. I've already written classes like Christoffel, Geodesic (which computes the geodesic equations),Constants-of-motions (which computes the constants of

Alexander, Brian expressed everything very well, and I am sure that your contributions will be very much appreciated! I worked on the tensor module[0] during the summer. At the moment, it doesn't really deserve its name: We have implemented indexed objects and implicit summation, but concepts l

Hi. I've seen what you have done and it's amazing!!! I still have a lot to learn. What I did was much simpler, but still I'll try to incorporate what I did in your code, though it would be a slow process since I'm actually working on cosmology, not exactly on computer programming. I'll start study
